VALVE-SPRING LIFTER. I

Specification of Letters Patent. Patented Sept. 28, 1920.

Application filed June 14,1919. Serial No. 304,227.

T 0 all to hom "it may concern:

Be it known that I, J OHN B. MEILER, a citizen of Switzerland, residingat New York, in the county of New York and State of New York, haveinvented new and useful Improvements in Valve-Spring Lifters, of whichthe following is a specification.

This invention relates to valve spring lifters and has for its primaryobject the provision of a tool of this class which is designed for usein compressing the spring to release its pressure from the valve andpermit the latter to be readily lifted when it is desired to re-grindthe faces of the seat or valve.

Other objects of the invention are to provide a tool of this characterwhich will be simple of construction, strong and durable and capable ofbeing quickly connected with ordisconnected from the work as theoccasion necessitates, and one which will be substantially universallyadjustable to suit many varying conditions.

lVith the above and other objects in view which will appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangements of parts which willhereinafter be fully described and particularly pointed out in theclaims.

In the accompanying drawings, has been illustrated, a single andpreferred form of the invention, it being, however, understood that nolimitations are necessarily made to the precise structural detailstherein exhibited, but that changes, alterations and modificationswithin the scope of the claims may be resorted to when desired.

Figure 1 is a side view of the tool showing the same applied in the actof lifting the valve from its seat.

Fig. 2 is a transverse section taken on the line 2-2 of Fig. 1 withparts in full lines.'

Fig. 3 is a section on line 3-3 of Fig. 1.

The tool comprises mating levers 5 and 6 which in this instance arearranged superposed. The lever 5 is provided with a post 7 having a stem8 arrangedto turn in said lever and as illustrated the said stem isupset at 9 against the lever. The companion lever 6 is provided with aswinging cylindrical socket member or sleeve 10 which is slidable on thepost 7. This arrangement provides for changing the leverage as theoccasion demands as the two levers are free to be adjusted relatively.In order that any required adjustment of the levers can be retained, itis preferred that the post 7 be provided with a longitudinal series ofpassages 11 which are arranged to register with similar threadedpassages 12 formed in the socket member 10. A pin 18 is adapted to bepassed through the registering passages 11 and 12 and connected therewith in a manner which will hold the post and the receiving socketmember against sliding movement.

The forward end of the lever 6 is pro vided with angularly disposedguide surfaces 14 and in the immediate proximity of said surfaces thelever is cupped at 15 to accommodate the washer 16 of the valve stem.The mating lever 5 has its forward extremity provided with similarangularly disposed surfaces 17 and said lever is provided with a cuppedportion 18 which is adapted to conform with the cam shaft plungercollar. By providing the angular surfaces 1l1land 17-17, it will beobserved that the levers can be quickly guided into position, whilethrough the arrangement of the cupped portions 15 and 18 it will bemanifest that when the levers are once positioned relatively of thevalve they can be maintained in such positions without fear of casualdislodgment. Through the fact that the post 7 is free to rotate itfollows that the lever 6 is adapted to turn in a horizontal directionwhereby the lever can be accurately associated with the valve stemirrespective of whether or not the forward extremity of the lever 5 isin exact vertical alinement with the forward extremity of the lever 6.The said forward ends of the levers 5 and 6 are uniformly bifurcated, asshown, and in view of the described manner of connecting said levers, itfollows that they can be rocked and also shifted laterally to cause thearms of said bifurcated ends to be relatively straddled or arranged sideby side in the same horizontal alinement. This connection of the partspermits the size of the lifting part of the tool to be materiallyreduced, which, when taken in connection with the surfaces 1414 and 1717enables the operator to conveniently guide the tool in position with thevalve structure.

The operating ends of the levers are provided with suitable hand gripsl9 and as shown a chain is suspended from one of said grips and thelinks thereof are adapted to be interchangeably connected with a hook 21on the grip of the other lever. In this manner it will be observed thatif the valve has been lifted and the spring compressed the levers can beheld in relatively fixed positions and the valve maintained'in anelevated position above its seat where the former and the latter will beexposed to permit them to be reground.

What is claimed as new is 1. A valve spring lifter comprising a pair oflevers, a post rotatabl'y supported from one of said levers, a socketmember slidable over said post and supporting the other lever forrocking movement, the said post serving to permit said other lever to berotated in a horizontal direction, and

means for holding the socket member fixed to the post.

2. A valve spring lifter comprising a pair of levers, a post rotatablysupported from one of said levers, a socket member slidable over saidpost and supporting the other ble connection with the other lever, tohold both levers in their set positions of adjustment.

3. A valve spring lifter comprising mating levers, said levers havingbifurcated forward ends in which the arms of said hifurcations areprovided with cupped portions, the cupped portion of the arms of onelever being reversely positioned with respect to the cupped portions ofthe arms of the other lever, and means operatively connecting saidlevers for vertical and horizontal swinging movements to permit thelevers to be'relatively separated and to also permit the arms of both ofsaid bifurcations to be relatively straddled when the levers areadjusted for initial application to the valve.

In testimony whereof I have aflixed my signature.

JOHN B. MEILER.
